How many #define sets do you expect? In other words, do you expect to have settings for each sketch or will several sketches have identical settings?
Less than a handful, and just two for now, just initial testing.
@maniacbug, thanks for the link, glad to know I'm not alone. I keep getting this feeling that I should explore getting out of the Arduino IDE some more. Have done some little work with WinAVR, but need to get smarter on makefiles.
@morris, indeed it is good at not linking in unused modules or functions. My approach was within several functions though, replacing lines of code here and there as needed. But certainly there are different methods, so maybe time to rethink the approach here. What I thought would be the path of least resistance turned out otherwise.
